Specification of Letters Patent.

Patented .hpri; 30, 1907.

Application filed A ril 27, 1906. Serial No. 313,955.

To all whom, it may concern:

Be it known that l, CONSTANT AILLERY, a citizen of the United States,and a resident of New Bedford, in the county of Bristol and State ofMassachusetts, have invented an Improvement in Loom-Shuttles, of whichthe following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

This invention relates to loom shuttles, and it has for its particularobject the production of novel and effective means for exciting theproper tension on the yarn or thread as it is drawn through theshuttle-e ye.

In my present invention I have provided a friction device around whichthe thread passes in contact as it turns from the longitudinal passagein the shuttle to the side delivcry-eye, the drag exerted upon thethread by engagement with the frictiondevioe keeping such thread underproper tension.

I have so arranged the friction device that it can be moved to bring afresh engaging surface into acting position when the old surface becomesworn.

The various novel features of my invention will be fully described inthe subj oined specification, wherein one practical embodiment of myinvention is set forth, and particularly pointed out in the followingclaims.

. Figure l'is a top lan View of the delivery end of a loom-shutt e, withone embodiment of my invention applied thereto; Fig. 2 is a sideelevation of the threading device or block detached, to more clearlyillustrate the tension-producing means; Fig. 3 is a front view of thethreading-block; and Fig. 4 is. an

enlarged cross-sectional detail on the line 4=-4, Fig. 2.

I have herein shown my invention enibodied in a loom-shuttle of theautomaticallyself-threading type, the threading device or block beingsubstantially that shown in United States Patent No. 769,914, grantedSeptember 13, 1904 to Northrop, but the particular threading device isnot material to my invention, and the latter may also be used in otherforms of loom shuttles.

Referring to Fig. 1 the shuttle-body 1 having an opening 2 to receivethe filling-carrier or bobbin 3, and the side delivery eye 4, may be allof usual construction. The metallic threadingblock 5 has a longitudinalthreadpassage 6 having a slot-lil-ze thread enirsnce 7 at its rear end,and at the from: end of the passage an inclined horn 8 is provided,Figs. 2 and 3, on the under side of the head 9 which overhangs thedeliveryeye. A beak it) crosses the front open end of tho thread-passage and is overlapped by a shield 11 the filllug-thread when drawn intothe thread-passage 6 and under the beak, being directed downwardautomatically by the horn 8 and adjacent parts of the threading blockinto the delivery-eye.

In my present invention I have provided a friction device which engagesthe-thread as it passes from the thread-passage and turns in a lateraldirection to the delivery-eye. A

steel pin' 12 depends from the threadingblock adjacent and back of thehorn, and ordinarily such pin serves as a fixed guide for the thread. Iprovide this pin or guide with a covering of friction-producingmaterial, such as felt, flaimel, or other suitable mate rial, the roughsurface thereof acting upon the thread and exerting the requisitetension producing drag or strain thereon. A convenient mode of applyingthe material is to cement or otherwise secure a piece 13 of the materialupon 'a cylindrical sleeve 14, slipped onto the pin and held thereonwith a frictional fit so as to be immovable or held from rotation undernormal conditions. It is unnecessary to head or upset the end of the pmas the bottom of the recess in the shuttlebody, out to receive thethreading block, will engage the lower end of the friction device andhold it in lace. When one portion of the surface of t we cylindricalfriction produc ing covering 13 becomes so worn that it will not actproperly upon the thread the block can be removed from the shuttle andthe covering turned slightly by hand to present a fresh friction surfaceto engage the thread.

From the location of the friction device it will be seen that thefilling-thread must draw across and partly around the same as it travelsalong from the front end of the threadpassage to the delivery-eye, andhence the tension is always exerted properly during the delivery of thethread. I

The construction herein shown and de" scribed may be varied or modifiedin different de tails by those skilled in the art without departingfrom. the spirit and see c of my in vention as set forth in the appen edclaims.

Having described my invention What I claim as new and desire to secureby Letters Patent isi i 1. In a loom-shuttle having a ileliver ve \'eand adap'ed to contain a suppl of filling, means to direct theiilling-tliread to theeve, a thread guide around which the thread passesto the (.leliverv-eye, and acovering of friction producing materialsurrounding and normally innnovable on said guide and acting upon thethreadv v 2. In a l0om-shuttle havinga side deliv er v-e, re and alongitudinal thread-passage, a fixed thread-guide around whieh thefillingthread passes as it travels from said passage to thedelivery-eve, and a covering oflfriction producing material mounted onand normally held from movelnem relative to said guide to engage thethread, said covering being adapted to beturned on the guide to presenta fresh engaging surface when de-' sired.

In testimony whereofll have signed my name to this specification, 111the presence of two subscribing witnesses.
